Key Parameters

Substitute Part Grouping Explanation

Substitution of the TBSL40K-TP is determined by strict equivalence across the following critical electrical parameters:

• Voltage - Peak Reverse (Max): 800 V
• Current - Average Rectified (Io): 4 A
• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant

The Z4DGP408L-HF manufactured by Comchip Technology meets all mandatory electrical specifications for direct substitution. Both components share identical peak reverse voltage, average rectified current, reverse leakage characteristics, and compliance certifications. Mechanical compatibility is maintained through surface mount packaging, though package case geometry differs (4-SMD Flat Leads versus Z4-D).

Parameter Comparison

Engineering Selection Recommendations

The Z4DGP408L-HF is a direct electrical equivalent for the TBSL40K-TP. Both components satisfy identical voltage and current specifications, making them functionally interchangeable in single-phase bridge rectifier applications rated for 800 V and 4 A operation.

The Z4DGP408L-HF offers the advantage of active product status with higher inventory availability (22,612 units in stock versus 1,123 units for the TBSL40K-TP). Both components maintain ROHS3 compliance and unlimited moisture sensitivity classification.

Forward voltage performance differs marginally: the TBSL40K-TP specifies 1 V maximum at 4 A, while the Z4DGP408L-HF specifies 950 mV maximum at 4 A. This 50 mV difference represents improved efficiency characteristics in the substitute part.

Operating temperature range extends to 175°C (TJ) for the Z4DGP408L-HF compared to 150°C for the TBSL40K-TP, providing additional thermal margin in high-temperature applications.

Frequently Asked Questions (FAQ)

Q: Can the Z4DGP408L-HF replace the TBSL40K-TP in existing designs?

A: Yes. Both components are rated for 800 V peak reverse voltage and 4 A average rectified current with identical reverse leakage characteristics. Electrical performance is equivalent for single-phase bridge rectifier applications.

Q: What are the package differences between these parts?

A: The TBSL40K-TP uses 4-SMD flat lead packaging, while the Z4DGP408L-HF uses Z4-D package geometry. Both are surface mount configurations. PCB layout and footprint modifications may be required for physical substitution.

Q: Does the forward voltage difference affect circuit performance?

A: The Z4DGP408L-HF exhibits 50 mV lower forward voltage (950 mV versus 1 V at 4 A). This results in reduced power dissipation and improved efficiency. No circuit redesign is required; the substitute part performs within acceptable operating parameters.

Q: Why is the TBSL40K-TP listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Z4DGP408L-HF maintains active product status with established supply chain availability.

Q: Are both parts RoHS compliant?

A: Yes. Both the TBSL40K-TP and Z4DGP408L-HF are ROHS3 compliant with moisture sensitivity level 1 (unlimited).
